A Study On Efficiency Of China's Small & Medium-Sized Commercial Banks M & A Efficiency

Small and medium-sized commercial banks are an important component of China's financial system. However, they are facing the growing strength of the competition and a series of problems in their development. Under such circumstances,Small and medium-sized commercial banks joins into bank merger in recent years. In that case,whether bank merger can bring efficiency becomes an important topic in academic community.Based on summarizing the former studies of ways to efficiency of M&A of banking,this paper chooses Operating Performance Study(OP) and three-stage DEA model to analysis the efficiency of M&A in China's Small and medium-sized commercial banks. The three-stage DEA model can estimate the efficiency through removing environmental and random factors. Thus,the efficiency can reflect the bank internal management ,so that we can judge integrating effect. In order to stress the importance of integration, we study practical measures of the bank.By analyzing and sampling, we come to the following conclusion: As stock commercial banks merger local small and medium-sized financial institutions, merger makes adverse effects to the efficiency of merging bank; Different type of foreign investors has different affects on merger efficiency. Financial investors pays great attention in the short-term benefit, only changes the bank operating results, they have not improve management levels by essentials. However, the strategic investor pays great attention in the long-term strategy, not only bringing the improvement to the operating performance, but also fundamentally improving the management of the bank. This attributes to the conformity integration after merger; Merger efficiency of the city Commercial banks are exposed to environmental and random factors heavily. We select the sample bank (Bank of Nanjing) belongs to the outstanding bank in the city Commercial banks. But,its efficiency fluctuates all the time ,and the level is low. This indicates that the city Commercial bank require further efforts in management and technological innovation.In view of the above conclusions, we put forward proposals from four aspects: improving the legal System, regulating government acts, formulating rational merger strategy and selecting oversea investor carefully.
